I’d say on the larger side of medium. The way I hold it I use my index finger for both L1/2 and the curve on the back (of the controller) makes it that I need to shift my grip when I wanna switch between them. I can hit the corner of L1 with the last knuckle, but it feels kinda off to do that.

I have the old NS09 (KK Pro) and NS39 (KK3 Max). The dongle latency is on par with bluetooth, which is not great. https://gamepadla.com/gulikit-kk3-max-kingkong-3-ns39.html

I’d say ymmv. I struggle reaching L1 while using the analog stick. Depending on a game, I’d often switch L1 and L2 around. It works, but it’s mildly annoying.

I also seem to have an issue with the face buttons double clicking sometimes. This doesn’t matter 99% of a time, but some games (Persona) don’t like it. It’s a shame, because otherwise it’s a fantastic controller.

Before this I had a 360 and 2 gulikit controllers and none of those had this issue. I actually really love the feel of the newer gulikit, unfortunately the wireless performance is atrocious.
